At 20 degrees Celsius, the density of air is 1.20 g/L. Nitrogen's density is 1.17 g/L. Oxygen's density is 1.33 g/L. Will balloo
1 answer:
Explanation:
Since, density is the amount of mass present in per unit volume.
Mathematically, Density =
As density is directly proportional to mass of a substance. So, more is the density of a substance more will be its mass. And, when more is the mass of a substance then it is likely to sink at the bottom.
Here, it is given that density of oxygen is more than the density of nitrogen. Therefore, balloons filled with oxygen will sink in the air.
On the other hand, balloons filled with nitrogen will rise in the air.

Answer : The correct option is B- Towards the left.
Solution : Given,
Force on car in upward direction, = 6000 N
Force on car in downward direction, = 6000 N
Force on car in right direction, = 5000 N
Force on car in left direction, = 6000 N
Force : Force is equal to the mass multiplied by the acceleration. The force is directly proportional to the acceleration.
Formula : F = m × a
where, F is force, m is mass and a is acceleration.
From the given diagram we conclude that the and
are in opposite direction and the force acting on car are same. So, their net force is zero.
And in case of and
, the net force will not be zero because force acting on car are different. The car will accelerate towards left direction because
is higher than the
.
So, the car will accelerate towards left direction.
